Long cold winter BLAHS

I've been finding this a hard winter, both in terms of weather and spirits. Work is less busy than it was 2 weeks ago, which is a blessing, but I've got a sinus infection that won't leave me and leads to sleepiness by day and for some reason, extremely vivid nightmares by night. I know neither the weather or the infection will last forever, just gotta put the head down and plough through both.
